Negative Hyper-Resolution for Proving Statements Containing Transitive Relations

Abstract

A modified version of PHR~- resolution comprising negative hyper-resolution and paramodulation is introduced to reduce the search of statements that contain transitive relations. Let R be a symbol of transitive relation and let a nucleus contain the literal tRp, and let a factor of an electron be of the form C V nt,Rt2.Moreover let us suppose that tU = t,U, where U is a simultaneous most general unifier for the corresponding clash. Then the resolvent of this clash contains the subclause (C V pRt2)U. This rule of deduction is said to Be TPHR- rule. It is shown that TPHR"- resolution is complete. More precisely, it is shown that the empty clause a can be deduced from a set G of clauses which contains the axiom of transitivity Tr for the relation R by using PHR""- resolution iff can be deduced from the set G-Trby using TPHR"- resolution. The efficiency of the use of TPHR~rule is illustrated by examples.
